Hi
Ich schwitze schon seit graumer Zeit an diesem Problem und es ist mir sogar zum Erklären kompliziert genug 
Ich will folgendes erreichen:
Ein Mikrofon hat, abhängig von seiner Richtcharakteristik, in jedem Winkel verschiedene Reichweiten.
z.B: Nierenform: von vorne kommen 100% ins Mikro, von hinten 0%
Ein Kugelmikro bekommt von rundherum immer 100% Schall
Nun will ich berechnen, wo bei 2 oder mehr aufgestellten Mikros die Trennlinie verläuft, also wo beide Mikros denselben Schallpegel empfangen
Zum besseren Verständnis bitte mal dieses Script ausführen:

Hier wird 360° um den Mitteplunkt die Formel in _CalcPoints angewandt, um die Richtcharakteristik zu berechnen

Erreichen will ich nun wie es folgendes Script zeigt:

Grob gesagt hab ich eine Formel, die um jeden Winkel um die eigene Achse verschienden Ergebnisse liefert und ich will herausfinden, wo die Grenze zwischen mehreren Mittelpunkten liegt...
Kann man das überhaupt berechnen, oder ist mein zweites Script (immer Bereich vergrößern und überprüfen, ob ein Punkt schon im "fremden" Bereich liegt) schon die beste Lösung?!
Ich hoffe, ich hab mein Anliegen gut genug erklärt, denn ich bin am Ende meines Lateins 
Danke
